There are four major styles of body jewelry which include the straight barbell, the circular barbell, the curved barbell and the ring. Each one of these styles is unique in their own way. Hope this guide helps, naturally there are other styles of jewelry, and other piercings, so if you are unsure check with your professional piercer or another reputable studio such as http://www.TheChainGang.com

Straight Barbell
The straight barbell is a straight bar that has a bead on each end, commonly on quality body jewelry only one bead can be removed to install or remove the bar with the other bead being “fixed” by soldering it to the bar. This way you are 50% less likely to lose a ball with only one being threaded. The reason this piece of jewelry has the name of barbell is that it resembles the barbells that you often see in weightlifting.
